Technical Field

The invention relates to a coupler alignment device used in coupler installation, and belongs to the technical field of transmission devices.

Background

The coupling is a mechanical part for coupling a driving shaft and a driven shaft in different mechanisms to rotate together to transmit torque. When the coupler is installed, alignment and centering of the coupler are the most critical steps, and determine the working state and the service life of a mechanism to be connected. The existing coupler alignment method is that a magnetic meter seat is adsorbed on the cylindrical surface of a coupler on one side, a meter rod fixed on the magnetic meter seat extends to the back of the coupler on the opposite side, a dial indicator is installed at the tail end of the meter rod, the dial indicator props against the upper part of the back end face of the coupler on the opposite side, and then measurement and adjustment are carried out. The method has the defects that the method is only suitable for the conditions that the position is proper, the axial length of the coupler is not too long or the spaces at two sides are larger, and when the axial length of the coupler is larger and a larger magnetic gauge seat cannot be used, the dial indicator sinks or swings when being installed, so that the measurement error is increased; when the spaces at the two sides of the coupler are narrow, the dial indicator can only be installed obliquely, and the accuracy of measured data cannot be guaranteed. In addition, when the calculated data relate to the diameter of the coupler, the existing coupler alignment method can only indirectly acquire the data from the rear end face of the coupler, so that the accuracy of the calculated result is reduced.

In summary, the existing coupler alignment method has a narrow application range and low measurement accuracy, and cannot ensure the installation quality of the coupler, so that improvement is needed.
